Milltek Sport Large-Bore Downpipes are designed to improve both performance and sound. These downpipes feature a larger diameter compared to standard OEM parts, allowing more exhaust gas to exit the engine and pass through, which increases efficiency. When combined with the Hi-Flow Sports Cat, a significant increase in performance and a noticeable change in sound can be expected. All Milltek Sport performance exhaust systems are manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for increased gas flow - Significant performance and sound improvement with Hi-Flow Sports Cat - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 70.00 - Fitment Time: 3 to 3.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - RH Primary Cat Rep Downpipe - MSBM267 - GPF/OPF Bypass Section with 200 Cell High Flow Cats - MSBM304 - LH Primary Cat Rep Downpipe - MSBM266 Vehicle Compatibility: - BMW 2 Series M2 Competition Coupe (F87) 2018 and later
